[0026] Reference Figures 1 to 4 , an embodiment of the present application provides a sheet metal leveling device, which may include a base 1, a first extrusion roller 2, a first driving component, a second extrusion roller 3, a second driving component, and a transmission component. The base 1 has a first seat surface and a second seat surface oppositely arranged in a first direction, and the first direction is the same as the thickness direction of the base 1; the first extrusion roller 2 is arranged on the side of the first seat surface away from the second seat surface, the axial direction of the first extrusion roller 2 is the same as a second direction and has the freedom to rotate about its own axis, and the second direction is perpendicular to the first direction; the first driving component is arranged on the side of the first seat surface away from the second seat surface and is connected to the first extrusion roller 2, and the first driving component provides a rotational driving force for the first extrusion roller 2; the second extrusion roller 3 is arranged on the side of the first extrusion roller 2 away from the base 1 and has the same axial direction as the second direction, and the second extrusion roller 3 has the freedom to move along the first direction and rotate about the second direction, and the first extrusion roller 2 and the second extrusion roller 3 extrude the sheet metal 7 to be leveled; the second driving component is arranged on the side of the first seat surface away from the second seat surface and is connected to the second extrusion roller 3, and the second driving component provides a moving driving force for the second extrusion roller 3; the transmission component is arranged on the side of the first seat surface away from the second seat surface and connects the first extrusion roller 2 and the second extrusion roller 3, and the first extrusion roller 2 drives the second extrusion roller 3 to rotate about the second direction through the transmission component in response to the rotational driving force, wherein the rotational direction of the first extrusion roller 2 is opposite to the rotational direction of the second extrusion roller 3.

[0027] An iron sheet leveling device proposed in an embodiment of the present application drives the second extrusion roller 3 to move away from the first extrusion roller 2 in the first direction through a second driving component. One end of the iron sheet 7 to be leveled is placed between the first extrusion roller 2 and the second extrusion roller 3, and then the second driving component is used to drive the second extrusion roller 3 to approach the first extrusion roller 2 in the first direction, so that the first extrusion roller 2 and the second extrusion roller 3 clamp the iron sheet 7 to be leveled. At this time, the first driving component is used to drive the first extrusion roller 2 to rotate, and the second extrusion roller 3 is driven to rotate through a transmission component. The rotation directions of the first extrusion roller 2 and the second extrusion roller 3 are opposite. In this way, when the first extrusion roller 2 and the second extrusion roller 3 rotate, they can drive the iron sheet 7 to be leveled to continuously move, so that the iron sheet 7 to be leveled passes between the first extrusion roller 2 and the second extrusion roller 3 for leveling. The second driving component controls the distance between the first extrusion roller 2 and the second extrusion roller 3, so that iron sheets of different thicknesses can be clamped for leveling, making it more convenient to use.

[0028] Specifically, as Figure 3 shown, the first direction is the X direction, and the second direction is the Y direction. If the base 1 is taken as a reference, the first direction X is the thickness direction of the base 1, and the second direction Y is the length direction of the base 1.

[0029] Furthermore, when the iron sheet leveling device is in use, the base 1 can be placed on a plane. At this time, the first direction X can be the same as the direction of gravity, and the first seat surface is located above the second seat surface.

[0030] It should be understood that when the second extrusion roller 3 moves in the first direction X, the transmission component is always connected to the first extrusion roller 2 and the second extrusion roller 3, so that when the first driving component drives the first extrusion roller 2 to rotate, the first extrusion roller 2 can always drive the second extrusion roller 3 to rotate through the transmission component, and the rotation directions of the first extrusion roller 2 and the second extrusion roller 3 are opposite.

[0031] Among them, as Figure 3 shown, the iron sheet leveling device may further include two support blocks 21. The two support blocks 21 are relatively fixed on one side of the first seat surface facing away from the second seat surface in the second direction Y. Among them, the first extrusion roller 2 is rotatably connected between the two support blocks 21, and the first driving component is arranged on one side of one support block 21 facing away from the other support block 21. In this way, the first extrusion roller 2 can rotate around the axis of the first extrusion roller 2 between the two support blocks 21.

[0032] Referring to Figure 3 , in an exemplary embodiment, the first driving component may include a mounting seat 41 and a motor 42. Among them, the mounting seat 41 is fixed to the base 1; the motor 42 is fixed on one side of the mounting seat 41 facing away from the base 1 and the axial direction of the output shaft is the same as the second direction Y; among them, the output shaft of the motor 42 is connected to the first extrusion roller 2.

[0033] Specifically, when the output shaft of the motor 42 rotates, it drives the first extrusion roller 2 to rotate synchronously. The motor 42 is located on one side of a support block 21 away from the other support block 21. At this time, one end of the first extrusion roller 2 close to the motor 42 penetrates through the corresponding support block 21 and is connected to the output shaft of the motor 42.

[0034] Among them, the first extrusion roller 2 can be connected to the output shaft of the motor 42 through a coupling, and the motor 42 is connected to an external power supply.

[0035] Reference Figure 3 , in an exemplary embodiment, the second driving assembly may include two limiting rods 51, two sliders 52 and two oil cylinders 53. The two limiting rods 51 are both fixed to the base 1 and extend along the first direction X; the two sliders 52 are sleeved on the outer circumferences of the two limiting rods 51 in a one-to-one correspondence and are slidably connected to the corresponding limiting rods 51. The sliders 52 have the freedom to slide along the first direction X. Among them, the second extrusion roller 3 is rotatably connected between the two sliders 52; the two oil cylinders 53 correspond to the two sliders 52 one-to-one and connect the corresponding sliders 52 to the base 1. The axial direction of the oil cylinder 53 is the same as the first direction X and has the freedom to expand and contract along the first direction X.

[0036] Specifically, both of the two sliders 52 are sleeved on the outer circumferences of the corresponding limiting rods 51 and can slide along the extending direction of the limiting rods 51. Then, the second extrusion roller 3 located between the two sliders 52 can also follow the two sliders 52 to slide along the extending direction of the limiting rods 51.

[0037] In the embodiment of the present application, by controlling the two oil cylinders 53 to expand and contract synchronously, the two sliders 52 can be driven to move synchronously in the first direction X, and finally the second extrusion roller 3 is driven to move in the first direction X. When the two oil cylinders 53 expand and contract synchronously, the second extrusion roller 3 will not tilt. Here, the tilt means that the axial direction of the second extrusion roller 3 is no longer parallel to the plane where the first seat surface is located.

[0038] Reference Figure 3 and Figure 4 , in an exemplary embodiment, one end of the first extrusion roller 2 away from the motor 42 penetrates through the support block 21; one end of the second extrusion roller 3 away from the motor 42 penetrates through the slider 52; the transmission assembly is located at one end of the first extrusion roller 2 away from the motor 42.

[0039] Specifically, in this way, the transmission assembly and the first driving assembly are oppositely arranged at both ends of the first extrusion roller 2 in the second direction Y, so that the center of gravity of the iron sheet leveling device is closer to the center of the base 1, and it is more stable when working.

[0040] Reference Figure 3 and Figure 4, in an exemplary embodiment, the transmission assembly may include a telescopic rod 61, two transmission cone pulleys 62, two driving cone pulleys 63, and a connecting portion 64. Among them, the telescopic rod 61 is rotatably connected to one side of the first seat surface facing away from the second seat surface. The telescopic rod 61 extends along the first direction X and has a degree of freedom of rotation around the first direction X; both of the two transmission cone pulleys 62 are sleeved on the outer periphery of the telescopic rod 61, and the distance between the two transmission cone pulleys 62 in the first direction X changes synchronously with the telescopic movement of the telescopic rod 61; the two driving cone pulleys 63 are respectively sleeved on the outer peripheries of the first extrusion roller 2 and the second extrusion roller 3, and the two driving cone pulleys 63 are in one-to-one correspondence and meshed with the two transmission cone pulleys 62; the connecting portion 64 is arranged on the slider 52 away from the motor 42 and is rotatably connected to one end of the telescopic rod 61 away from the base 1.

[0041] Specifically, for the convenience of distinction, the driving cone pulley 63 and the transmission cone pulley 62 connected to the first extrusion roller 2 are denoted as the first cone pulley and the second cone pulley, and the first cone pulley and the second cone pulley are meshed; the driving cone pulley 63 and the transmission cone pulley 62 connected to the second extrusion roller 3 are denoted as the third cone pulley and the fourth cone pulley, and the third cone pulley and the fourth cone pulley are meshed; when the first extrusion roller 2 rotates, it will drive the first cone pulley to rotate around its own axis, the first cone pulley drives the second cone pulley to rotate around the extension direction of the telescopic rod 61, the second cone pulley drives the telescopic rod 61 and the fourth cone pulley to rotate around the axis of the telescopic rod 61, and the fourth cone pulley further drives the third cone pulley and the second extrusion roller 3 to rotate, and the rotation directions of the first extrusion roller 2 and the second extrusion roller 3 are opposite; at the same time, when the second extrusion roller 3 moves along the first direction X, it drives the connecting portion 64 to move along the first direction X through the slider 52, the connecting portion 64 drives the telescopic rod 61 to expand and contract. At this time, the fourth cone pulley moves synchronously with the expansion and contraction of the telescopic rod 61, so that the fourth cone pulley and the third cone pulley are always in a meshed state. In this way, after the second extrusion roller 3 moves along the first direction X, the first extrusion roller 2 and the second extrusion roller 3 can still be driven to rotate in opposite directions by the motor 42.

[0042] Reference Figure 3 , in an exemplary embodiment, in the first direction X, the two transmission cone pulleys 62 are relatively arranged on one side where the two driving cone pulleys 63 are away from each other.

[0043] Specifically, as Figure 3 shown, in this way, even when the first extrusion roller 2 and the second extrusion roller 3 are in contact, a relatively long distance is always maintained between the two transmission cone pulleys 62, that is, between the second cone pulley and the fourth cone pulley, giving enough installation space for the telescopic rod 61.

[0044] Reference Figure 3 and Figure 4, in an exemplary embodiment, the telescopic rod 61 may include a sleeve 611 and a piston rod 612. The sleeve 611 is connected to the base 1. Wherein, a driving cone pulley 62 is sleeved on the outer periphery of the sleeve 611; the piston rod 612 passes through one end of the sleeve 611 away from the base 1 and has the freedom to slide along the first direction X. Wherein, another driving cone pulley 62 is sleeved on the piston rod 612.

[0045] Specifically, the sleeve 611 is rotatably connected to the base 1, that is, the sleeve 611 can rotate around its own axis but cannot move along the first direction X. The second cone pulley is sleeved on the outer periphery of the sleeve 611; the piston rod 612 can be splined to the sleeve 611, so that torque can be transmitted between the sleeve 611 and the piston rod 612, and at the same time, the telescopic movement of the piston rod 612 is not affected. The fourth cone pulley is sleeved on the outer periphery of the piston rod 612. In this way, when the piston rod 612 moves along with the second squeezing roller 3 through the connecting portion 64, the third cone pulley and the fourth cone pulley move synchronously and are always in a meshing state. After the second squeezing roller 3 moves along the first direction X, the first squeezing roller 2 and the second squeezing roller 3 can still be driven to rotate in opposite directions by the motor 42.

[0046] Reference Figure 3 And Figure 4 , in an exemplary embodiment, the connecting portion 64 may include a swivel ring 641 and a connecting member 642. The swivel ring 641 is sleeved on the outer periphery of the piston rod 612 and is rotatably connected to the piston rod 612. The swivel ring 641 has the freedom to rotate around the first direction X; the connecting member 642 is fixed to the outer periphery of the swivel ring 641 and is connected to the corresponding slider 52.

[0047] Specifically, the swivel ring 641 is rotatably connected to the piston rod 612, so that the swivel ring 641 does not affect the normal rotation of the piston rod 612; the connecting member 642 is fixed to the outer periphery of the swivel ring 641 and is connected to the corresponding slider 52. In this way, when the second squeezing roller 3 drives the slider 52 to move along the first direction X, the slider 52 drives the connecting member 642, the swivel ring 641 and the piston rod 612 to move synchronously.

[0048] Reference Figure 1 , in an exemplary embodiment, the iron sheet leveling device may further include a housing 11. The housing 11 is disposed on the side of the first seat surface away from the second seat surface and encloses a receiving cavity with the base 1. The first squeezing roller 2, the first driving assembly, the second squeezing roller 3, the second driving assembly and the transmission assembly are all located in the receiving cavity. A strip-shaped hole 111 for the iron sheet 7 to be leveled to pass through is provided on the housing 11.

[0049] Specifically, the first extrusion roller 2, the first drive assembly, the second extrusion roller 3, the second drive assembly, and the transmission assembly are all arranged in the accommodation cavity, which can greatly reduce the dust falling on the first extrusion roller 2 and the second extrusion roller 3, prevent the surface of the first extrusion roller 2 and the second extrusion roller 3 from being uneven due to dust, and ensure the flatness of the iron sheet after leveling. At the same time, the outer shell 11 can play a good protective role for the first drive assembly, the second drive assembly, and the transmission assembly.

[0050] It should be understood that there are two strip-shaped holes 111 and they are oppositely arranged on the outer shell 11. The iron sheet 7 to be leveled passes through one strip-shaped hole 111 and enters between the first extrusion roller 2 and the second extrusion roller 3, and the leveled iron sheet extends out of the outer shell 11 from the other strip-shaped hole 111.

[0051] Furthermore, the outer shell 11 can be made of a transparent material to facilitate the observation of the leveling process and the working conditions of each component.

[0052] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present application.
